vboot: allow more flexibility when adding verstage 

When a separate verstage is employed the verstage file
was just being added through the cbfs-files mechanism.
However, that doesn't allow one to specify other flags
that aren't supported that an architecture may require.
The x86 architecture is one of those entities in that
it needs its verstage to be XIP. To that end provide
a mechanism for adding verstage with options.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built and booted glados using his mechansim on x86.
